To all 'who-mbit may concern:

Beit knownv thatL-CHARLES N. WURTH,

i a. citizen of the United States, residing at ."O'ran'ge, the4 county of Essex and State of New Jersey, have ,invented certainnew and useful Improvements'in Feeding Mechanism for Phono'graphs andother Machines, of whiehlthe following isjja description.

vrecorder of a'phonogra h5 whereby the'same is fed transversel vto-.t ie direction ofmove-A ment of the sur ace o f' the-record'- and the stylus traverses aspirahpat-h 'on the record,

- `lunjordf'miry phonographsnow in use, it.

hasbell usual top rovide al feed screw -havdredtliso'f an inch. .As records can now bel much smaller pitch,

naryhonograph may-v bey adapted for the Vrecel" 1n' (ir-reproductioncf records having either-o` 'the above, or any other desired itch', lhislobject' accomplish-by the pro- "uction 'f'i'rnproved means whereby the carriage may be advanced either directly bythe rotating feed screw, as has hitherto been the practice, or whereby, at the will of the operator the carriage may be advanced at each revolution rof the feed screw, a distance bearing any desired ratio to the pitch of 'the saidl screw.

another object of my invention is to provide 'a 's'i'ni'le attachment adapted' to' be readily 'app 'ied'fto 4 existing phonographs to adapt the same for use with records of different pitches.

With these and'other objects in mind, my

invention consists of the 'features hereinafter set forth-and claimed. 11i order-that my invention may be more fully understood, attention is hereby directed to the accompanying drawing, forming a part of this specification and in .ivhilfl-- Q Figure 1 is a plan of a phonograph prov'idedwith a feeding device constructed in "y 'accordance with my invention; Fig.l :'Zris an by' Ia simple manipulation Specication of :Letters fatent. 5 Patented fillg'. 2.0. 191.2. i Application lediibruary 2', '1911.

end elevation of the device shownin Fig. 1,

, the feed screw being shown in section taken' 55 on the line-2 2 of Fig. 41; and'Fig..3 is a section ofiny improved feeding device taken on the line3-3 of Fig. 1. Corresponding parts are designated by the same reference numerals in the several views. The phonograph shown is' of the :Edison type and comprises the usual body 1 having a back rod 2 on which the traveling carriage\ 3 provided with an arm 3 for supporting a recorder o r reproducer is mo'vably mounted. 6E The mandrel i is mounted upon the main shaft. which vis provided 'with a feed screw 6 which, as has been explained, ordinarily has a pitch of one one-hundredth of an inch, although a screw of different pitch may be used'. A pulley 6 `is secured to/the sha-ft 5.

Thepresent invention compri/ses a worm wheel 7 for engarement with the 4feed screw 6, the said wormwheel being secured to one end of 'a shaft 8 which is supported in a 75 suitable bearing 9, which in'turn. is carried by the traveling carriage 3, 4 The lbearing 9 is detachably connected-to the trav'elinr carriage by the resilient member 10. 'lo'the opposite e'nd ot' the shaft 8 from that carry'- 80 ing the wornrwheel 7 is secured a ulley 11 having a groove 12 in its: peripeiiyf A thumb screw 13 )rovided with' a'knurled head 14 is carried by the bearing' Sand is ada ted to be brought into contact with the 85 shatt 8 whereby tl'ielatte'r'may b e secured against rotation.V -A. cord 15' or .any other suitable equivalent means is fixed at one end to the spring hook 16 carried b the body 1 and is passed around the pul ey11, the 90 other end of the cordbeing fixed to the body by means of the block 17 movablealong the body and provided with" a set screw 18 whereby itmay be' secured in position. A tension spring 19 `is'interpmied be# 95 tween the end of the cord 15 and the block 17. By means of `the adjustable block 17 aud the spring 19, any desired amount'of tension may be imparted to the cord, the resiliency of the spring prevent-ing the cord from being subjected toexeessive strains. As shown in Figs. 1 and 2, the pulley 11 and the cord 15 are located in proximity to the back rod 2, 'so that theZarm 3' ma. beraised through a considerable angle wit lout 'interference from the cord 1 5.

m wm..

The operation of my device vis as fol. l

said feed screw lfor moving said carriage .in

lows z-Power being applied to the pulley 6', the feed screw and the mandrel will revolveat a certain speed. When theI thumb screw 13 is brought into contact with the shaft 8, -the worm wheel is held against ro tation, and acts, von the rotation of the'fe'ed screw, precisely like an ordinary feed nut; and the carriage advanced .at each revo 10 lution of the feed screw a distance. equal .to

the pitch of the said screw. During the operation of the device as described above,.

the cord slips over the pulleyv as the worm wheel advances,such operation being.

15 facilitated-by the resiliency imparted to the cord by the spring 19. 'When it is desired to employmy improved device with records havingla different pitch from that of the feed scrc'w,:.the thumb screwf13 is `moved out-of .engagement with. thesliaft 8. The eed"screwlbeing then actuated, the worm wheel-'1f und pulley 1 1 are revolved, the pulleyv11 is shifted longitudinally .of the-record by its engagement with the cord 15, an.d the carriage is advanced at each rotation of the .feed screw adistance depending upon the pitch diameters of the worm wheel 7 and the pulley 11;` Y.

IVhile I have described my invention as applied to a phonograph for prodiicingthe` desired feed of the carriage, it is obviouslynot limited to such use, and may be applied te any mechanism whatever for converting 4rotary movement into progressive lineal movement.
